START-UP PROCEDURE
B. FILL AND PURGE HYDRONIC HEATING LOOP
Freeze Protection (When Used)
1.
Determine freeze protection fluid quantity using total system water content of 1/2 gallon.
Remember to include expansion tank water content and follow fluid manufacturer’s
instructions.
2.
Local codes may require back flow preventer or actual disconnect from city water supply.
3.
When using freeze protection fluid with automatic fill, install a water meter to monitor water
make-up. Freeze protection fluid may leak before the water begins to leak, causing
concentration to drop, reducing the freeze protection level.
The power must remain off until the Hydronic heating loop is fully purged of air.
1.
Fill the system after ensuring the water quality meets the water quality standards outlined
within this manual (See Part 3, Section H). This will ensure years of trouble free operation.
2.
Close manual and automatic air vents and any drain valves in the hydronic system loop.
3.
Fill to correct system pressure. The correct pressure will vary with each application.
a. Typical system pressure is 15 PSI
b. Pressure will rise when the hydronic module starts to heat from the heated water from the
domestic side of the system. Operating pressure must never exceed the relief valve pressure
setting of 30 psi.
c. At initial fill and during start-up and testing, check system thoroughly for any leaks. Repair all
leaks before proceeding further.
4.
The system may have residual substances that could affect water chemistry. After the
system has been filled and leaked tested, verify that water PH and chlorine concentrations
are acceptable by sample testing.

WARNING
Eliminate all system leaks. Continual fresh make-up water will reduce the Hydronic
Heating Module Heat Exchanger ability to effectively transfer heat which will reduce
the heating module performance.

WARNING
Never use automotive or standard glycol antifreeze, or ethylene glycol made for
hydronic systems. Use only freeze – prevention fluids certified by fluid manufacturer as
specified for use with Stainless Steel Hydronic Heating Module Heat Exchanger and
verified in fluid manufacturer’s literature.
Thoroughly clean and flush any system that has used glycol before connecting up to
the Stainless Steel Hydronic Heating Module Heat Exchanger. Provide (MSDS) material
data safety sheet o fluid used to owner.
CAUTION
It is important that you purge the system of air to avoid damage to the Modulating Pump.
